public class MindsensorsLightSensorArray
extends I2CSensor

MindSensors Light Senor Array
This sensor an array of 8 sensors with controlled light source, returning you values of the sensor readings.

The code for this sensor has not been tested. Please report test results to the leJOS forum.

Supported modes
Mode name	Description	unit(s)	Getter
Red	Measures the light value when illuminated with a red light source.	N/A, normalized	getRedMode()

Sensor configuration
The sensor can be calibrated for black and white using the calibrateWhite and calibrateBlack methods.

The sensor can be put in and out of sleep mode (lights off) using the sleep method and wakeUp methods.
